The ion content ion content was measured and analyzed by inductively and 15 mmol/LCaCl2 , respectively.

The mean values represented by the distinctive letters were sigaverage SD of three independent replicates. The imply values represented by the various letters nificantly different in Tukey’s test at p 0.05. were substantially distinct in Tukey’s test at p 0.05.3.10. Effects of of Exogenous Calcium on Plant Phenolic Finafloxacin supplier compounds below Salt Anxiety three.10. Effects Exogenous Calcium on Plant Phenolic Compounds beneath Salt Strain Subsequently, we studied the accumulation of phenolic compounds in in distinctive Subsequently, we studied the accumulation of phenolic compounds different tissues tissues treated with 100 mmol/L NaCl (S1), 100 NaCl + ten mmol/L CaCl (S1 + C2), and treated with one hundred mmol/L NaCl (S1), 100 mmol/L mmol/L NaCl + 10 mmol/L CaClnormal growth state (CK). Visualization of phenolic components was performed by hierarchical cluster analysis (Figure 6). Twenty-three phenolic compounds and L-phenylalanine have been determined by the LC S technique in methanol extracts of roots, stems, and leavesAgriculture 2021, 11,11 ofof G. sinensis, and the sorts of compounds measured for the differently treated samples showed no difference. It may be noticed in the heat map that these compounds have been primarily divided into three groups on the basis of their tissue-specific accumulation patterns and participated in salt stress responses to varying degrees. The C6C3-type compound (p-hydroxycinnamic acid, p-coumaric acid), the C6C3C6-type compound (naringenin, glycyrrhizin, genistein, quercetin), and L-phenylalanine were mainly accumulated within the roots (Figure 7A). There was a slight enhance but not considerable within the case of salt treatment alone, along with a very important boost in case of exogenous calcium addition. The C6C1type compound (two,5-dihydroxybenzoic acid) plus the.
